Under warm 2700K interior light Royal shifts subtly: leans toward purple, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.8), so it is a lighting-stable choice.

Against white it measures 13.47:1 and against black 1.56:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black text on this color entirely.
One color explored: close hues with real lightness and chroma structure, so the palette is the anchor through value rather than a set of colors.
#789aed · #4f71cf · #2948b1 · #0c1793 · #030053 · #010015
The anchor's neighbours on the wheel — everything shares an undertone, so the chord carries color without anything having to be muted to get along.
#005a7f · #00447b · #0c1793 · #23006d · #200041 · #150020
The mid-gap pairing — sage and mustard, terracotta and olive. A foil rotated 40–65° toward warm or cool: too far to be kin, too near to argue, carried by temperature and a deliberate value offset.
#c290d0 · #5c81e3 · #9638af · #643b6f · #0c1793 · #040061
One deliberately opposed voice — a single restrained counterpoint across the wheel, or temperature against temperature where the anchor is too muted to carry a loud opposite.
#f3bb00 · #556da8 · #425071 · #0c1793 · #050f48 · #00001b
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#faf1de · #abb7d0 · #847e71 · #3f4b65 · #0c1793 · #241d0c
This color as a ground rather than a subject — its own restraint held across a narrow value band, carrying one saturated voice from the opposite temperature.
#f6f1e6 · #d0cbbe · #a6a091 · #332b19 · #110900 · #0c1793
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#fff1d1 · #e1ae1b · #9e7800 · #5f4700 · #0c1793 · #09174a
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#fff1d1 · #ff9a49 · #7b8800 · #733900 · #0c1793 · #1c2000
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedeb · #ff948a · #009933 · #005c1b · #0c1793 · #400002
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
